I think I would need a few examples of "emotional side of a relationship" and a few examples of "non-emotional side of a relationship" in order to answer.
I love my husband very much. He's kind and loyal, and a good match for me. He's a good father, and very sweet. He likes a lot of the same things I do, but also has interests that are his own. He loves me, too. We sometimes tell each other we love each other, or say kind things. But mostly we talk about movies, money, the kids, our hobbies, and stuff.
I can't imagine us sitting down for a long discussion about our feelings, though, if that's what's meant by "emotional side of a relationship." I mean, how much can you discuss something like that. "I love you." "Oh, I love you, too. I'm glad I've got you." "Me, too! Would you like a cup of tea?" "Oh, yes please!" I mean, what else is there to say?
I wouldn't want to be in a soap opera kind of relationship, spending hours on end trying to get my husband to prove that he loves me, or to set him up so I can somehow catch him in the act of not loving me (whatever that means.) If that's what "emotional side of a relationship" means, then I certainly don't have any of that. That, to me, seems very juvenile.
I suppose this means that I really don't understand what it means to have an emotional side of a relationship. I feel like my relationship is healthy and successful. I've had other, shorter-term relationships which I think were healthy and successful, but each one was started with the understanding that it would end at some point, like a partnership. They weren't completely devoid of emotions, but I don't think there was a specific "emotional side".
Whatever. I don't know. I don't think I have any specific abhorance for the expression of emotions, though. It's just not a big deal.
